Low adhesion compositions of perfluoropolyethers
Abstract
A coated article is provided. The coated article has a substrate having a low surface energy coating thereon, said coating comprising an in situ polymerized monofunctional poly(perfluoropropyleneoxy) acrylate or methacrylate oligomer. The oligomer has a poly(perfluoropropyleneoxy) segment, [CF(CF3)CF2O]d, which has a number average molecular weight of about 800 to 25,000.
